We are facing an issue while connecting the ESP32 device with the Android mobile using ESP32 WiFi. We have tried to connect the mobile device and ESP32 manually by using ESP32's SSID and password. It seems to be, when the ESP32 signal strength is good/excellent then the android mobile get connects to the ESP32.
And when the ESP32 signal strength is poor then the android mobile not connects to the ESP32. We have tested the issue on various android device version (6.0, 6.0.1,7.0, 8.0, 8.1 etc.) But, it sometimes works or sometimes may not work due to the poor ESP32 signals.

Each of the above mentioned devices were at the equal distance (i.e. 2 Meter range) from the ESP32 device while I was checking for the connection issue.

Are you setting ESP32 in AP mode, and the trying to connect your smart phone with the ESP32 SoftAP ?
2 meters shouldn't get the signal poor like that.
Can you read the RSSI from the phones ?
Which hardware are you using?
Could it be that the antenna is missing ?
